Remarks

An app doesn't need to decipher or manipulate CanvasJustificationOpportunity data in order to perform justification. The array of justification data from GetJustificationOpportunities(CanvasCharacterRange, CanvasFontFace, Single, CanvasAnalyzedScript,Int32[] ,CanvasGlyphShaping[] ) can simply be passed to ApplyJustificationOpportunities(Single,CanvasJustificationOpportunity[] ,CanvasGlyph[] ) unmodified. Exposing CanvasJustificationOpportunity data gives apps the opportunity to customize justification behavior.
